What the documents look like
For document comparison in General import declarations, this page examines FastGPT document chunking. Outer-case dimensions and goods specifications need separate field identities after parsing. The examples are hypothetical.
Constraints at the document chunking step
A proposed import contract attachment supplies no measurements. It says goods specifications are in a technical sheet and outer-case dimensions serve loading arrangements, with a footer excluding packaging material as a goods specification. A product-dimension question therefore reaches a reference to another page, while the case field has a limited purpose. Parsing and chunking should preserve both scopes. The appearance of dimension terminology in one file cannot turn case information into product data or create technical-sheet content that was not supplied in this proposed packet.
Configuration and implementation checks
| Original or chunk check | Specific source relationship | Evidence action |
|---|---|---|
| Specification reference | Goods details in technical sheet | Retain uninspected source identity. |
| Packaging purpose | Cases serve loading arrangements | Check no transfer to goods properties. |
| Footer condition | Packaging is not goods specification | Keep condition with relevant block. |
| Parsed order | Technical reference beside case field | Inspect incorrect joining. |
| Added-sheet retest | Technical-sheet identity and applicable goods | Check processing, indexes and new citations. |
Documented conditions
| Documented item / implementation check | Condition |
|---|---|
Original-document check | Compare original files with parsed output. |
Chunk completeness | Keep conditions traceable to their subjects. |
Data and indexes | Retain original-data and index evidence separately. |
Sample retrieval | Retest literal wording and natural questions. |
Post-update check | Inspect training or index state after updates. |
Three common errors
One failure puts the footer in a separate block, leaving outer-case information without its specification exclusion. Another joins a technical-sheet reference to an adjacent case heading as if the latter supplied the referenced content. Compare original layout, parsed order and actual blocks to locate separated conditions or merged membership. A product-dimension index still needs its target original inspected; query vocabulary cannot turn packaging purpose into a goods property. An intact document title also does not establish the field-level relationships required to read these entries correctly.
How to verify the setup
Acceptance should search goods-specification and outer-case terms, then ask whether the available contract actually states product dimensions. The answer should distinguish supplied information from an uninspected reference. If the technical sheet is obtained, verify its identity and applicable goods before processing and index checks, then repeat the question to inspect actual new citations. The earlier packaging block remains useful for loading but cannot prove goods specifications. Successful technical-sheet upload alone cannot establish that the dimension question is fully supported; inspect the original text and returned content.
